The aim of this randomized controlled clinical trial is to examine single-tooth implant abutments and restorations in the esthetic zone. Restorations will be fabricated using two different techniques. Zirconia CAD/CAM (ZCC) implant abutments and restorations will be compared to conventional, prefabricated Titanium (TCF) implant abutments and porcelain-fused-to-metal restorations using reproducible aesthetic (objective/subjective) and biologic parameters.
